-## Plugin[Beta]
-
-The plugin allows users to rewrite Claude Code prompt and custom router. The plugin path is in `$HOME/.claude-code-router/plugins`. Currently, there are two demos available: 
-1. [custom router](https://github.com/musistudio/claude-code-router/blob/dev/custom-prompt/plugins/deepseek.js)
-2. [rewrite prompt](https://github.com/musistudio/claude-code-router/blob/dev/custom-prompt/plugins/gemini.js)
-
-You need to move them to the `$HOME/.claude-code-router/plugins` directory and configure 'usePlugin' in `$HOME/.claude-code-router/config.json`，like this:
-
+4. Configure routing[optional]
+Set up your `~/claude-code-router/config.json` file like this:
 ```json

 }
 ```
+- `background`    
+This model will be used to handle some background tasks([background-token-usage](https://docs.anthropic.com/en/docs/claude-code/costs#background-token-usage)). Based on my tests, it doesn’t require high intelligence. I’m using the qwen-coder-2.5:7b model running locally on my MacBook Pro M1 (32GB) via Ollama.
+If your computer can’t run Ollama, you can also use some free models, such as qwen-coder-2.5:3b.
+
+
+- `think`    
+This model will be used when enabling Claude Code to perform reasoning. However, reasoning budget control has not yet been implemented (since the DeepSeek-R1 model does not support it), so there is currently no difference between using UltraThink and Think modes.
+It is worth noting that Plan Mode also use this model to achieve better planning results.    
+Note: The reasoning process via the official DeepSeek API may be very slow, so you may need to wait for an extended period of time.
+
+
+- `longContext`   
+This model will be used when the context length exceeds 32K (this value may be modified in the future). You can route the request to a model that performs well with long contexts (I’ve chosen google/gemini-2.5-pro-preview). This scenario has not been thoroughly tested yet, so if you encounter any issues, please submit an issue.
+
+
+- model command   
+You can also switch models within Claude Code by using the `/model` command. The format is: `provider,model`, like this:     
+`/model openrouter,anthropic/claude-3.5-sonnet`    
+This will use the anthropic/claude-3.5-sonnet model provided by OpenRouter to handle all subsequent tasks.

 ## Some tips:
+Now you can use deepseek-v3 models directly without using any plugins.
+
 If you’re using the DeepSeek API provided by the official website, you might encounter an “exceeding context” error after several rounds of conversation (since the official API only supports a 64K context window). In this case, you’ll need to discard the previous context and start fresh. Alternatively, you can use ByteDance’s DeepSeek API, which offers a 128K context window and supports KV cache.
